Step 1: What You Need
Pathfinder uses several different kinds of dice, each with a different number of sides. When referring to dice, you use the letter "d" followed by the number of sides on the die. For example, a standard six-sided die would be called a d6. If you are expected to roll multiple dice, there will be number before the "d". For example, rolling four six-sided dice (or a single six-sided die four times) would be written as 4d6.
B. You will need the following dice to play using the Pathfinder system: d4, 4d6, d8, d%, d12, and d20.
The d% refers to two dice: one is a normal d10 referred to as the "ones," and the other is a d10 with the numbers 0-90 on it in multiples of 10, referred to as the "tens." When rolled simultaneously, these dice allow for 100 different possibilities, hence the name d%. For example, a "40" on the tens die and a "6" on the ones die give the result 46. Note that when rolling a d10, a roll of "0" is actually 10. When rolling a d%, a roll of "0" on the ones die and "00" on the tens die is actually 100.
